BUTTER-DISH MACHINE.

SPECIFICATION forming part of Letters Patent No. 361,138, dated April 12, 1887.

Application filed April 5, 1886. Serial No. 197,807. (l\ 'o model.)

To attain the desired end my invention consists, essentially, in certain novel and useful combinations or arrangements of parts and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure 1 is a vertical longitudinal section of my machine at line as a: of the horizontal section, Fig. 2. Fig. 3 is a plan view of the pivoted former. Fig. 4 is a plan View of a dish as scored and cut before shaping. Fig. 5 is afront view and partial section of my machine.

Like letters of reference, wherever they occur, indicate corresponding parts in all the figures.

A is the bed-plate, supported uponlegs B. The forming-plate A is pivoted to the bed at a.

E is the driving-shaft, provided with a pulley, E, for receiving the driving-belt, a pinion, E, being located upon the extremity of the shaft opposite to said pulley.

F is the main operating-shaft of the machine, carrying the two crank gear-wheels F F". Wheel F is provided with teeth upon only one-third of its periphery, sufficient to turn roller G one complete revolution, permitting it to remain at rest while the wheel F completes its revolution.

A continuous moistened sheet of veneering is fed to the machine upon table B, passing between the feed-rollers G and G, and as the roller G revolves the knives g thereon score that portionof the sheet which forms the blank for the dish Y at 9'. (See Fig. 4.) If desired, at the sametime that the scoring is performed by roller G any characters may be printed or impressed upon the blank by means of a die or by the use of ink laid upon type secured to n, H, H, H", H, and HA or formed upon said roller, said inking-roller being illustrated,as K, Fig. 1. After the scoring operation the veneer is cut, as hereinafter described, and the sheet of veneering remains stationary until the next revolution of the rollers G G, which upon their second rotation move the veneering along, and it passes between rollers l I and J J, which are rotated by pinion F through the medium of pinions As the wheels F and F revolve, the eccentric crank-pins F depress the rods F, carrying a connectingbar, F resting in groove F in top formingplate, A, the top plate, A, being thereby depressed until the knives a upon said top plate cut the wood of the blank Y at a Fig. 4, the knives a cutting against or across plates 0 O of bed-plate A, and the knives a upon three sides of top plate, A, cut across or against the knives G O of the bed plate A on the line a of the blank Y, Fig. 4.

One depression of the top plate, A, cuts out a blank, Y, on the line a", and at the same time the material 'is cut on the line a of blank Y, as above described,for the next blank. Springs 61 under plates D serve to raise the sheet of Veneering in order to make it feed more readily.

The top plate, A, is provided with lugs M, to which the slotted link or is pivoted. This said link engages in the forked arm N, fulcrumed at n to the main frame. The other extremity of arm N connects through links 0 and 0 with across'piece, O, carrying a hollow rod, P, and cross-piece 19, attached to the lower end of said hollow rod. This hollow rod P is held and slides vertically within a fixed sleeve,

A, supported by a bracket, A

11 is aplunger-plate supported by the formerplate A. The plunger-plate is provided with four guide-rods, a, at each corner, which extend through apertures a (see Fig. 3) in the forming-plate A. These guide-rods are surrounded on the upper side of the plate A by spiral springs, which normally hold the plunger-plate 1) up against the under side of the plate A and inclosed by the knives a In Figs. 1 and 5 the plunger-plate is shown depressed by the downward movement of the rod P and cross-piece 19, said cross-piece coming in contact during its descent with the upper surface of the plunger-plate and forcing ICO it downward against the resistance of the springs.

Located and sliding within the hollow rod P is a second rod, 10 which carries on its lower end an auxiliary plunger-plate, w. This auxiliary plate fits in a circular aperture, e in the plate 1), between thearms of the crosspiece 1?. Normally, the rod 10" and plate to are held upward by a spring, in", so that the plate w" is held with its lower surface flush with that of plate 1). The rod w slides vertically within and independently of the hollow rod P, and it is actuated by the following mechanism: The upper end of the rod 10 is fastened to a bar, 10, extending crosswise of the machine. (See Fig. 5.) The opposite ends of this bar are connected to vertical operating-arms w'w, which are pivoted near their lower ends to the outer ends of levers V V. (Shown in Fig. 1 in dotted lines.) These levers, which are of the first class, are pivoted to a fixed part of the frame-work, and their short arms are so located that they are in the paths of eccentric pins or studs ff, carried by the crank-wheels F F Vhen in the rotation of the wheels F F the crankstuds f f encounter the levers V V, the long arms of the levers are depressed, and with them the arms '10 w, rod to and auxiliary plungerplate w.

Immediately beneath the knives a a of the former-plate A are folders aa, which are hinged to the bed-plate immediately adjacent to the aperture therein, through which the plungers w and 1) pass. These folders are normally horizontal, and are hinged so as to fold upward and toward each other. Each folder has on its under side a small bracket, I, (see Fig. 5,) which enters a slot in the bedplate. To this bracket is pivoted a down wardly-extcnding link, Z, which is also pivoted to one end of a lever, Z, of the first class, which in turn is pivoted to a fixed portion of the machine. A retracting-spring, Z", connected to this lever and to the fixed frame, holds the folder normally in its horizontal position. The outer ends of the levers Z l are so located that they are encountered by tappet bell-crank levers ZZ, carried by the arms w 10, during the descent of the latter. tappet-levers Z l are pivoted to the arms '20 10, so that they may swing freely past the levers Z 1 during the upward movement of the arms '10 w.

Beneath the bed-plate is a chute, 13 into which the plungers p andw descend, and upon the lower end of which the receiver B for the finished plates is removably held. This chute has two vertical sections, 8 s, the lower section, s being of thesmaller diameter, and these two sections are connected by an inclined section, 8.

The operation of the machine is as follows: The veneering or thin strips of wood from which the dishes are to be made is fed in between the feed and scoring rollers G G, which make the scores 9 g. Vhen the veneering The has been further fed forward, the movable former-plate A descends and its knives do make the cuts a a in the veneering. Vhen the former-plate A makes its next descent, the veneering has been fed forward so far that the scored and cut portion is immediately beneath the knives a a and pluugers p and to. As the former-plate descends it carries with itthe plungers, and just after the knives a d cut out the edges of the blank Y the plunger 29 de scends, pushing the blank Y downward upon the folders a. The plunger 10'' is pressed down by and with the plungerp, and with it the rods 10 w, and just as the two plungers press the blank in contact with the folders the tappetlevers Z Z encounter the levers l I, thus pressing up the folders. The shape of the plunger 1) and of the opening through which it passes, it will be seen, on comparing Figs. 2 and 4, conforms to the shape of that portion of the body of the blank which is between the opposite seored lines, gg, the same being numbered 1, 2 2. The parts outside of those lines-that is, parts 3 3, 4t 4, 4 4-are brought down by the plungers into contact with the folders. The folders, turning upward, bend these parts 3 4 upward, each part bending at the scored lines g,- and, owing to the scored lines of the parts 4 being at an angle to those of parts 3, the edges of parts 4. adjacent to those of parts 3 will be slightly within those of parts 3. The farther descent of plunger 12', which descends a short distance beneath the folders, presses the blank downward through the aperture in the bedplate. The bent-up parts 3 47 are prevented from folding back by contact with the walls of the chute B Vhen the descent of the main plunger ceases, the blank is just above the inclined section 8 of the chute, and at this point the eccentric studs ff encounter the levers V V, and the auxiliary plunger w is then depressed independently of the main plunger. The auxiliary plunger presses against the central portion, 1, of the blank, pushing it downward, and the parts 22 are turned up and the parts 4 4 are bent within the parts 3 3 by coming in contact with the inclined section 8" of the chute B When the blank has been pushed entirely within the lower section of the chute, the descent of the plunger 10 ceases, and on the several parts returning to their elevated positions the sequence of operations is complete. As the lower section, 8, of the chute becomes filled with the bent blanks they are forced downward into the receiver 13 The veneering used for making the dishes is wet when used, and the dishes are left in the receiver until they are perfectly dry. when taken out of the receiver, they retain their bent position. Before ready for the market, however, the parts 3 and at are usually se cured together by metallic clips.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a device of the character herein specified, the scoring and feed rollers G G, the pivoted cutting-plateA, the bed-plate adapted to said cutting-plate, and the folding mechan-' ism, combined, adapted, and arranged to automatically operate substantially as shown and described. v
